The state-run SANA news agency reported the speech would "reassure the Syrian people."

The pro-government rally on Tuesday followed violent clashes between protesters and security forces in the cities of Daraa and Latakia in recent days. At least 37 people have been killed since last week, according to the U.N. Office of the High Commissioner for Human Rights.

Syria is the latest in a string of Arabic-speaking nations beset with discontent over economic and human rights issues. Syria's discontent is centered in Daraa, a southern city in the impoverished country's agricultural region, where security forces and anti-government protesters have sporadically clashed for nearly two weeks.

Many demonstrators at the pro-government rally held posters of the president. Others waved Syrian flags, while some painted their faces and chests in national colors.

Crowds filled the square in front of the Central Bank and jammed all roads leading to it, aerial pictures on state TV showed.

There were also pro-government rallies in the cities of Aleppo, Hama and Hasaka, the broadcaster said.
